| − | *• Have designed 7 solar mini grids for rural areas of Bangladesh<br/>• IDCOL- provides funding for development of mini-grids in Bangladesh<br/>• Funding then comes from international founders<br/>• 50% is grant, loan and smallest portion is equity: financial model designed for 20 years<br/>• Household condition surveyed before the project (feasibility study)<br/>• For 800 households: the financial model does not look good enough for the demand because the majority of the demand is at night. The cost of electricity is almost 3times higher if use electricity at night than in the day<br/>• Battery management: life, charging and discharging, duty (kept it at about 50%)<br/>• Keep diesel generator as a backup and to make up the rest of the hours that are not generated by PV<br/>• Distribution feeders not distributed more than 5km<br/>• During winter the day demand reduces because of electric fund. But irrigation demand. 10-15 irrigation plants integrated in the winter season can make up for the lack of demand (compared to summer)- reduces the cost of energy<br/>• Most costly is the storage system of the project<br/>• Advantage of diesel- battery very small- do not use it for night storage<br/>• 17 kw power can be handled by 1 inverter<br/>• Small households have one room and one toilet<br/>• Largest pack –of consumers-school<br/>• Solar irrigation- irrigation farms only operate during daytime- installed separate feeders- energy started with light and shut off with sunset<br/>• Need management people for any type of system and about the same number<br/> | + | *IDCOL- provides funding for development of mini-grids in Bangladesh. 50% is grant, loan and smallest portion is equity: financial model designed for 20 years<br/> |
